To Our Clients:

Enclosed for your consideration are the Offer to Purchase, dated September 21, 2023 (what we refer to as the “Offer to Purchase”), and the related Letter of Transmittal (what we refer to as the “Letter of Transmittal” and what, together with the Offer to Purchase, as each may be amended or supplemented from time to time, we refer to as the “Offer”) in connection with the offer by Peregrine MergerSub I, Inc., a Delaware corporation (which we refer to as “Merger Sub”) and a wholly owned subsidiary of GXO Logistics, Inc., a Delaware corporation (which we refer to as “Parent”), to purchase all outstanding shares of common stock, par value $0.001 per share (which we refer to as “Shares”), of PFSweb, Inc., a Delaware corporation (which we refer to as “PFSweb”), at a purchase price of $7.50 per Share, in cash, without interest thereon and less any applicable withholding taxes, upon the terms and subject to the conditions of the Offer.

THE BOARD OF DIRECTORS OF PFSWEB HAS RECOMMENDED THAT STOCKHOLDERS TENDER ALL OF THEIR SHARES TO MERGER SUB PURSUANT TO THE OFFER.

We or our nominees are the holder of record of Shares held for your account. A tender of such Shares can be made only by us as the holder of record and pursuant to your instructions. The Letter of Transmittal accompanying this letter is furnished to you for your information only and cannot be used by you to tender Shares held by us for your account.

We request instructions, by completing, executing, detaching and returning to us the Instruction Form on the detachable part hereof, as to whether you wish us to tender any or all of the Shares held by us for your account, upon the terms and subject to the conditions set forth in the enclosed Offer to Purchase and the Letter of Transmittal.

Please note carefully the following:

1.	The offer price for the Offer is $7.50 per Share, in cash, without interest thereon and less any applicable withholding taxes.

2.	The Offer is being made for all outstanding Shares.

The Offer is being made in connection with the Agreement and Plan of Merger, dated as of September 13, 2023 (together with any amendments or supplements thereto, what we refer to as the “Merger Agreement”), among Parent, Merger Sub and PFSweb, pursuant to which, after the completion of the Offer and the satisfaction or waiver of the conditions set forth therein, Merger Sub will be merged with and into PFSweb, with PFSweb surviving the Merger as a wholly owned subsidiary of Parent (which we refer to as the “Merger”), without a vote of the stockholders of PFSweb in accordance with Section 251(h) of the General Corporation Law of the State of Delaware.

4.	The Offer and withdrawal rights will expire at 12:00 midnight, New York City time, on October 20, 2023, unless the Offer is extended by Merger Sub or earlier terminated.

5.	The Offer is not subject to any financing condition. The Offer is subject to the conditions described in Section 15 of the Offer to Purchase.

Tendering stockholders who are record owners of their Shares and who tender directly to Computershare Trust Company, N.A. (the “Depositary”) will not be obligated to pay brokerage fees, commissions or similar expenses or, except as otherwise provided in Instruction 6 of the Letter of Transmittal, stock transfer taxes with respect to the purchase of Shares by Merger Sub pursuant to the Offer.

If you wish to have us tender any or all of your Shares, then please so instruct us by completing, executing, detaching and returning to us the Instruction Form on the detachable part hereof. An envelope to return your instructions to us is enclosed. If you authorize tender of your Shares, then all such Shares will be tendered unless otherwise specified on the Instruction Form.

Your prompt action is requested. Your Instruction Form should be forwarded to us in ample time to permit us to submit the tender on your behalf before the Expiration Time.

The Offer is not being made to, nor will tenders be accepted from or on behalf of, holders of Shares in any jurisdiction in which the making of the Offer or acceptance thereof would not be in compliance with the securities, “blue sky” or other laws of such jurisdiction. In those jurisdictions where applicable laws require the Offer to be made by a licensed broker or dealer, the Offer shall be deemed to be made on behalf of Merger Sub by one or more registered brokers or dealers licensed under the laws of such jurisdiction to be designated by Merger Sub.
